在Java10中，尝试导入java.awt或javax.swing时遇到cannotresolved错误。解决方法是在SystemLibrary中将Executionenviroment版本从javaSE-10改为J2SE1.5，以兼容AWT组件。

摘要生成于 C知道 ，由 DeepSeek-R1 满血版支持， 前往体验 >

在java10中，导入java.awt或javax.swing都会报cannot resolved，这个问题也困扰了我一个下午，最终解决方法是将

System Librory 中的 Execution enviroment版本修改，可能在新版本的库中中，awt不存在了？我也不清楚，反正最终解决了

在JRE System Library目录下的desktop中有awt包

 我右键单击JRE Sytem Library，选择properties

然后将javaSE-10换成J2SE1.5

改完以后就成功了

     今天下午，帮师兄在MyEclipse中配置我原来做的“基于支持向量机的时序预测系统”。出现了这么一个问题“javax.swing.GroupLayout cannot be resolved"，很明显，是GroupLayout类无法识别，其他类都没问题，因此肯定是jdk的问题。由于使用的MyEclipse为6.0.1-GA版的，jdk为1.6.0.04的。想了下，jdk挺新的啊，应该有G
